SHORT TERM /THROUGH THURSDAY/

Issued at 240 PM CDT Wed Apr 8 2026

Wind will continue to gust between 45 to 50 MPH late this afternoon into the early evening with winds diminishing after 6 PM with gusts up to 25 MPH into the early evening hours. A cold front is forecast to move across the area this evening and bring a band of showers and isolated thunderstorms across the area from northwest to southeast from late this afternoon through sunrise on Thursday. Rainfall amounts will be light with 1 to 2 tenths of an inch possible. The front is forecast to stall along a roughly Fairfield to Galesburg line or just to the south of there. Low temperatures are forecast to range from the mid 30s northwest of a Cedar Rapids to Dubuque line.

Showers and thunderstorms are possible in the vicinity of the front Thursday afternoon. High temperatures on Thursday are forecast to range from the upper 50s along the Highway 20 corridor to the lower 70s in far southeast Iowa, west central Illinois and far northeast Missouri. Clouds will also be limited to near the front through the day with west to northwest winds across the area with speeds of 5 to 10 MPH. Rainfall amounts through the day are expected to be light with less than a tenth of an inch.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/

Issued at 240 PM CDT Wed Apr 8 2026

The aforementioned front will have since stalled out over the area, with guidance generally keeping it between Interstate 80 and Highway 34 in Iowa. Thus, this has trended south since the last forecast package. This is important because this boundary will act as a focal point for rounds of showers/storms later Thursday PM, as a weak shortwave tracks towards the area from the west. This wave and the LLJ setting up Thursday evening and night will provide the necessary moisture and forcing for persistent showers and storms Thursday evening into Friday morning. More widespread rainfall is expected overnight throughout the area, with the persistent rounds of rainfall focused in our south along the boundary, where we will see the rainfall chances persist into Friday morning. We will see a nice soaking rainfall with this, where the recent dry days should allow for easy infiltration of the rainfall. Areas along and north of Interstate 80 will generally see between 0.50-0.75" of rain through the night, with those south of the interstate seeing upwards to 1.00" of rainfall. Localized amounts upwards to 1.25" will be possible.

Much of the area will remain dry on Friday after this rain moves out, with the rain moving out of our south by the afternoon hours. With this, high pressure will start to work towards the area, resulting in decreasing cloud cover from north-south and light winds. Temperatures will also be near 60, resulting in a pleasant day to close out the work week.

High pressure and associated ridge push east Saturday into Sunday, with upper level flow becoming more southwesterly. This would favor strong WAA into the region, especially on Sunday. Saturday will serve as the transitional day, which should keep us largely dry with temperatures in the 60s. Going into Sunday, we see a more potent wave eject off of the southern Rockies and track northeast into the Central Plains. LLJ will set up Saturday night ahead of this wave, which may result in overnight showers/storms, especially with a weak leading shortwave passing through. Surface low will then follow a similar track as the main wave, with leading shortwaves bringing chances for precipitation Sunday into Monday. Without a baroclinic zone stalled over the area, we are not expecting a focused area of heavy precipitation at this time. Rather, scattered showers and storms will result, especially with increasing instability. Monday into Tuesday, we will see the associated cold front pass through, largely in the evening and overnight hours. With decent forcing and instability in place ahead of the front, some stronger storms cannot be ruled out. This was highlighted by the SPC yesterday, where they had a Day 7 15% chance for severe weather in our south, equating to a level 2 of 5 risk for severe weather. Although, there is plenty of time for this forecast to change. Thus, just keep in mind that chance for stronger storms is out there, but will have to continue to monitor forecast trends.

AVIATION /18Z TAFS THROUGH 18Z THURSDAY/

Issued at 1223 PM CDT Wed Apr 8 2026

Gusty south winds will continue through the afternoon with gusts up to 40 knots possible at KCID and KDBQ with up to 35 knots at KBRL and KMLI. A cold front will move across the area from west to east after 03 UTC turning the winds to the west then northwest. Winds diminish after 03 UTC with speeds of 5 to 10 knots through the remainder of the period. Showers are possible along the front between mainly 3 to 8 UTC. Thunderstorms are possible but there is low confidence that they will occur. MVFR conditions are possible in showers otherwise VFR conditions are expected through the period.
